Doug Croxall, Marathon's Chief Executive Officer, stated, "These transactions with Siemens not only materially increases our asset count to now 631 U.S. and foreign patents, with 79 patent applications, but importantly, it will expand Marathon's patent licensing activity into Asia, while remaining active in both the United States as well as countries in Europe. Many of the newly acquired assets have been declared as SEPs and we intend to assert our patent rights, wherever infringed. In addition, the transaction further diversifies Marathon's portfolio coverage into a vibrant and growing technology sector -- IOT."
